CVE-2021-26349amdepyc_72f3_firmware+23
EPSS score0.22%
Failure to assign a new report ID to an imported guest may potentially result in an SEV-SNP guest VM being tricked into trusting a dishonest Migration Agent (MA).CVE-2021-26370amd2nd gen amd epyc™+50EPSS score0.23%
Improper validation of destination address in SVC_LOAD_FW_IMAGE_BY_INSTANCE and SVC_LOAD_BINARY_BY_ATTRIB in a malicious UApp or ABL may allow an attacker to overwrite arbitrary bootloader memory with SPI ROM contents resulting in a loss of integrity and availability.CVE-2021-26343amd3rd gen epyc+24EPSS score0.18%
Insufficient validation in ASP BIOS and DRTM commands may allow malicious supervisor x86 software to disclose the contents of sensitive memory which may result in information disclosure.CVE-2021-26397amd3rd gen amd epyc™+23EPSS score0.18%
Insufficient address validation, may allow an
attacker with a compromised ABL and UApp to corrupt sensitive memory locations
potentially resulting in a loss of integrity or availability.CVE-2021-26376amdathlon™ series+85EPSS score0.22%
Insufficient checks in System Management Unit (SMU) FeatureConfig may result in reenabling features potentially resulting in denial of resources and/or denial of service.CVE-2021-26379amd2nd gen amd epyc™+49EPSS score0.68%
Insufficient input validation of mailbox data in the
SMU may allow an attacker to coerce the SMU to corrupt SMRAM, potentially
leading to a loss of integrity and privilege escalation.CVE-2021-26398amd1st gen epyc+66EPSS score0.21%
Insufficient input validation in SYS_KEY_DERIVE system call in a compromised user application or ABL may allow an attacker to corrupt ASP (AMD Secure Processor) OS memory which may lead to potential arbitrary code execution.CVE-2021-26339amdathlon™ series+85EPSS score0.28%
A bug in AMD CPU’s core logic may allow for an attacker, using specific code from an unprivileged VM, to trigger a CPU core hang resulting in a potential denial of service. AMD believes the specific code includes a specific x86 instruction sequence that would not be generated by compilers.CVE-2021-26342amdepyc_7001_firmware+38EPSS score0.22%
In SEV guest VMs, the CPU may fail to flush the Translation Lookaside Buffer (TLB) following a particular sequence of operations that includes creation of a new virtual machine control block (VMCB). The failure to flush the TLB may cause the microcode to use stale TLB translations which may allow for disclosure of SEV guest memory contents. Users of SEV-ES/SEV-SNP guest VMs are not impacted by this vulnerability.CVE-2021-26354amd2nd gen amd epyc™ processors+169EPSS score0.18%
Insufficient bounds checking in ASP may allow an
attacker to issue a system call from a compromised ABL which may cause
arbitrary memory values to be initialized to zero, potentially leading to a
loss of integrity.CVE-2021-26324amd3rd gen amd epyc™+23EPSS score0.27%
A bug with the SEV-ES TMR may lead to a potential loss of memory integrity for SNP-active VMs.CVE-2021-26364amdepyc_7232p_firmware+44EPSS score0.22%
Insufficient bounds checking in an SMU mailbox register could allow an attacker to potentially read outside of the SRAM address range which could result in an exception handling leading to a potential denial of service.CVE-2021-26316amd1st gen epyc+152EPSS score0.26%
Failure to validate the communication buffer and communication service in the BIOS may allow an attacker to tamper with the buffer resulting in potential SMM (System Management Mode) arbitrary code execution.CVE-2021-26356amd1st gen amd epyc™ processors+105EPSS score0.40%
A TOCTOU in ASP bootloader may allow an attacker
to tamper with the SPI ROM following data read to memory potentially resulting
in S3 data corruption and information disclosure.CVE-2021-26388amdathlon™ series+108EPSS score0.22%
Improper validation of the BIOS directory may allow for searches to read beyond the directory table copy in RAM, exposing out of bounds memory contents, resulting in a potential denial of service.CVE-2021-26344amdamd athlon™ 3000 series desktop processors with radeon™ graphics+83EPSS score0.16%
An out of bounds memory write when processing the AMD
PSP1 Configuration Block (APCB) could allow an attacker with access the ability
to modify the BIOS image, and the ability to sign the resulting image, to
potentially modify the APCB block resulting in arbitrary code execution.CVE-2021-26345amd2nd gen amd epyc™ processors+94EPSS score0.43%
Failure to validate the value in APCB may allow a privileged attacker to tamper with the APCB token to force an out-of-bounds memory read potentially resulting in a denial of service.CVE-2021-26353amd3rd gen epyc+23EPSS score0.27%
Failure to validate inputs in SMM may allow an attacker to create a mishandled error leaving the DRTM UApp in a partially initialized state potentially resulting in loss of memory integrity.CVE-2021-26378amdathlon™ series+85EPSS score0.22%
Insufficient bound checks in the System Management Unit (SMU) may result in access to an invalid address space that could result in denial of service.CVE-2021-26396amd3rd gen epyc+24EPSS score0.11%
Insufficient validation of address mapping to IO in ASP (AMD Secure Processor) may result in a loss of memory integrity in the SNP guest.
